Practical Tips
Beakers are used as reaction vessels for preparing solutions, dissolved substances and larger amounts of substances at room temperature or under heating.
1. When heating the beaker, an asbestos mesh should be placed on it to provide uniform heat. Do not use a flame to directly heat the beaker. Because the bottom of the beaker is large, direct heating with a flame will only burn part of the glass, causing uneven heating of the glass and causing it to burst. When heating, the outer wall of the beaker must be wiped dry.
2. When used for dissolution, the amount of liquid should not exceed 1/3 of the volume of the beaker. And stir gently with a glass rod. During the dissolving or diluting process, when stirring with a glass rod, do not touch the bottom or wall of the cup.
3. When holding liquid for heating, do not exceed 2/3 of the volume of the beaker. Generally, 1/3 of the volume of the beaker is appropriate.
4. When heating corrosive chemicals, cover the mouth of the beaker with a watch glass to prevent liquid from splashing out.
5. Do not use beakers to hold chemicals for a long time to avoid falling into dust and evaporating the water in the solution.
6. Do not use beakers to measure liquids.
